The exact cause of dandruff, also known as scurf or Pityriasis simplex capillitii is unknown. However, most experts do agree that it is not caused by poor hygiene. In this MNT article, we look at the possible causes as well as potential treatment options. So, what are the factors that may contribute to dandruff?
Not enough hair brushing
People who do not comb or brush their hair regularly have a slightly higher risk of having dandruff – this is because they are not aiding the shedding of skin that combing or brushing provides.
People who are sensitive to yeast have a slightly higher risk of having dandruff, so it is logical to assume that yeast may play a part. Yeast-sensitive people who get dandruff often find that it gets better during the warmer months and worse during the winter. UVA light from the sun counteracts the yeast. Some say, that during winter the skin is drier because of cold air and overheated rooms (exposure to extreme temperatures), making dandruff more likely. So, it is sometimes not that easy to know whether it is yeast or just dry skin.
People with dry skin tend to get dandruff more often. Winter cold air, combined with overheated rooms is a common cause of itchy, flaking skin. People with dandruff caused by dry skin tend to have small flakes of dandruff; the flakes are not oily.

Seborrheic dermatitis (irritated, oily skin)
People with seborrheic dermatitis are very prone to dandruff. Seborrheic dermatitis affects many areas of the skin, including the backs of the ears, the breastbone, eyebrows, and the sides of the nose, not just the scalp. The patient will have red, greasy skin covered with flaky white or yellow scales.
Not enough shampooing
Some people say that if you don’t shampoo enough there can be a buildup of oil and dead skin cells, causing dandruff. However, many experts doubt this is true.
